Headache now now headache later.
I put one of these on the rear MTB ebike hub conversion just because it is a bit more to deal with changing a tube and to protect the rim in the event of a flat. The front does not have the tire insert. What the front does have that the back does not it the little tiny wet spots from all the goathead punctures it is getting. It was a bit of a pain to install but after 50 miles no punctures while the front is testing the limits of the slime. The front is getting one of these liners as well I believe.

Finally got em for my 27.5 rims. Installation was easy, trimmed the ends and they fit perfectly. Tube placement went smoothly.
Aired them up a little and made sure the tires were seated properly, they look good & no wobble. Inflated to 25psi for now.
Test ride coming up!
3 - 32 mile rides later and I’ve got no complaints. So far, very good !!
Glad I got them.

While I think the idea of this is super cool and groundbreaking for cyclists, they aren’t the easiest to get into your tires. I bought these for my 27.5” mtb but struggled getting them inside the tire. It was nearly impossible to then get the tube inside these, so after 20mins and some YouTube videos later I gave up and decided to return. I rate them 5 stars because I think they’ll do what they say they will, and would be great to have the confidence of not getting a flat. Maybe I’ll try them again down the line in a different bike

I kept popping my rear inner tubes I’m guessing because I’m too heavy I weigh about 240 and I’m an extremely rough rider so I do wheelies and lot of tricks. I was a little hesitant because of the price but after reading reviews this looked like a good fit for me. Installation wasn’t that bad, it takes a little time to sneak the foam into the right places but if you follow the instructions and dont force anything you’ll be fine. After installation my tire feels so much more stronger without putting in a lot of air and the ride is still solid, the tire still feels the same weight I don’t notice any difference. Overall this transformed my bike tire it feels like it has a ton more strength than ever. I would recommend to anyone who has an issue pinching the inner tube.

There was nothing I could do to get this product installed on either of my bike's wheels. I followed the instructions and trimmed the liner since I have a 26x2.125 tire, did not fit. I tried trimming a little more, still not even close to fitting. I have the recommend size tubes of 26x1.5-1.95.

The box sports a warning of:
"In some cases, the size of the Armour will not match the size of your tire. If proving difficult to install, we recommend changing size."

Prior to trying to install Tannus Armour, my bike previously had double-tires on each wheel. That is, an outer tire with a wire bead, then under that an inner tire (with the wire bead cut off so that it could fit inside the outer tire), then an extra thick heavy duty 26x1.50-1.95 tube. I never had a flat with the double-tires method even though I've had to pull multiple nails out that were several inches long. It was difficult to install and not all people may be strong enough to do it, but I actually had success with installing double-tires unlike Tannus Armour.

The inner tires I used were literally just garbage old tires I had laying around that I meant to throw away but ended up reusing after reading about the double-tire method. Meanwhile, a pair of Tannus Armour is $100.

Literal garbage old tires were an easier to install tire liner than Tannus' offering, and in their service life of a little less than a year they had no flats. Even if I bought new tires to repurpose as a tire liner, it would cost almost half of what Tannus Armour is going for. It seems no matter how I look at it, Tannus Armour is a bad deal compared to the options available.

I first installed Tannus on my rear wheel because that was where all my flats occurred. No more flats after that! It worked so well I installed one in the front wheel about a year later. I have experienced no flats since using these inserts and I ride on and off road. The inserts were difficult to install. I managed on my own for the rear tire but I absolutely could not install the tire on the front rim. I got everything in place inside the tire but the last foot of rubber would not go on the rim. I went to my local bike shop for help. The tech needed ten seconds to get the tire on the rim. Ten seconds! I asked how he did it and he just told be he'd been doing it for years. So, don't be put off by the difficulty of installation. Your LBS can take care of it for you.

My bike has 27.5 x 2.35" mountain bike tires installed. Some people have remarked that their ride feel changes after installing these inserts. I have not noticed much difference since using Tannus. The wheels are more sensitive to the amount of air in the tubes. I used to run 50-55 lbs air pressure but now I inflate to 40. Some people run less air with these inserts. I have read stories with tires at 10-20 lbs but you will get a more squishy ride at that low pressure. Experiment with different values to see which works best for you. Note: If your bike is going to sit idle for a while (weeks or longer), I recommend you deflate the tires. This will allow the foam to expand back to its original size and the tires will be ready when you inflate for your next ride.

I can recommend the inserts. I have nothing but good to say since installing them. They are pricey but I loathe flats and will do anything to help avoid them.

(I have a 29x2.4 tire, got the appropriate armor and have a tube of 1.75-2.4) Installation was a little harder than I imagined, but easy enough, it worked! just brought it out for the first test run and went on runs that have given me multiple holes from punctures, snake bites... and so far so good! i'm excited to keep pushing it. I'll update with more hard hits and either flats or lack of flats! I've also been paranoid cause I'm a heavier guy around 240-250 with all the gear.
also PSI, i previously ran around 28ish, and they recommend staring 5psi lower. I was paranoid and started at 30psi which was too much, so probably stick with their recommendations, i'm still honing in on my preference- but it doesn't feel grossly different so far from running tubeless when i have it dialed

update (after a couple months) completed The Whole Enchilada and they worked perfectly, I have not had any issues with flats and the tires have performed well. Also done Goosebury Mesa, only needed to top off the tires before each run. I also noticed as some point there was multiple goat heads/thorns, had no issues with flats still

Llevo 3 meses usándolas y no he pinchado una sola vez, mientras que antes cada salida era al menos una ponchadura (rodada en montaña, ponchaduras por espinas principalmente). Pesan un poco más las ruedas pero no es algo que realmente no puedas uno manejar con um buen entrenamiento. Sensación un poco diferente a llantas normales, pero terminas acostumbrándote (casi imperceptible con doble suspensión). Muy recomendables.

Size: 700 x 35-40cVerified Purchase
I'm unsure if I will continue to use. They were easy to install but had problems with a slight wobble that took a week of fiddling to make go away. Tannus advises to deflate tire after each ride to maximize longevity. This is a pain because it brings the wobble back requiring fiddling around again. They definitely prevent pinch flats. I run around 30 psi and like the plush feel over rocks. The trade off is rolling resistance is much higher. I'm undecided between running latex tubes at 40 psi with tire sealant resulting in faster rolling and noticeable difference in weight when climbing. I'm heavy so if I get pinch flats with my latex setup I will switch back to the Tannus. Tires are WTB 700 x 42c Resolutes
